Scratch start TIG is still being used a lot for high quality pipe welds. Its a very simple and basic Tig welding system that works very well for pipe welding. The main drawbacks are ...no remote amperage control, and not being able to shield the weld where you terminate the arc. This video shows a few tips and a diy foot switch.

Not only an excellent welder, but an excellent teacher with a rich vocabulary, and a good knowledge of physics and precision, who does not prefer the rule of thumb and keep the instruments in the drawer as most people I know often do.
A good man, congratulations.
After watching thousands of videos, this is the first one I've seen by someone that is not an idiot. Thank you.
can you do a diy video on making a foot switch like in the video? and all the specs on all the parts you had to use please. it'd be a huge help for myself and I'm sure others
thanks!

I like the middle bit where you talked about torch sizes. That kind of info is just assumed to be known or to have been taught to a beginner. I would've like to have known about that when I was first starting out. You are the only teacher many folks have! Keep up the good work Jody. I still love my TIG finger.
Just want to thank you for all your hard work Jody. I've recently started a TIG welding class at my local community college only a month after starting my stick class at the recommendation of my instructor. I am learning scratch start because the machine I am using doesn't have a pedal attachment to use for TIG. I have been looking at getting a multiprocess welder that way when I start the MIG class I will be able to do that on top of stick and TIG. Your videos have been super helpful in seeing how I need to do certain things. I have learned that practice is king with this stuff and I hopefully will soon have a welder to practice at home with.
Hi Jodi , May I say I really enjoy watching your videos. Because of you my welding has come on in leaps and bounds. Even learnt to scratch start tig. More vids like these please. Your an amazing teacher, clear and to the point with a bit of humor. Thank you once again. Tom Greene, Ireland
Hey Jody. I'm trying to keep you and others videos going here because folks have a really hard time with things and because of you it's simplify. Thank you and God bless you
Awesome video Jody, thank you so much. I always enjoy your tig welding lessons on round tube copes, which are the most difficult for me, and what I want to do most frequently. You make it look easy, which gives me confidence. Thanks again!
I have been welding for 10 years, about a year ago I had an opportunity to learn to tig weld for the first time, I had a crash course in it as the members of my crew quit when I had to learn to scratch start tig on stainless in a yogurt plant, short story, I feel in love with tig welding, and now that I know I can do it at home with the equipment I already have that allows me to practice whenever I can so I can go after those good jobs that seemed unobtainable for a regular ole structural welder, so I just wanted to say thanks for all you do here on youtube your vids are very good and informative, and im buying my tig finger just as soon as I get payed again, nice job bro, keep it up
Thanks so much Jody, Cant overstate how much value these videos add to me as a welder. Thank you for investing in the trade as a whole.
another great video Jody. I know your experienced, but I'm still amazed at your comfort level and how easily you move around the work material. that's my major problem to this day is leaving myself enough room to move and being comfortable (not tense) to smoothly move around the weld work. I do dry runs, but still end up getting in my own way.
Nice to watch a master craftsman at work. Thanks for showing.
Great welding man your the best I have seen on UA-cam
Hey great video I have a scratch start tig and I made that foot switch and it is so much easier to stop welding and the welds look so much cleaner, I wish I could show you it somehow it turned out pretty good!
Great video jody .i learnt to weld watching your videos started of with a scratch start rig and used the torch switch to activate a solenoid for the gas.and your tig fingers are great
Thanks helped me a lot, it had been many many years since i had done any tig welding. I had the situation where it just wasn’t getting a nice flow going and took a while to pool, it was my angle and ark distance. I just purchased a similar machine for the shed , very capable unit. Thanks agian
Thanks for the tip on metalgeek. I have a Miller Bobcat and 2 wire machines but I like the looks of TIG. I'll have to see if my Bobcat will work. Thanks again for sharing!
Great video as always Jody. I learn so much and that's why I always buy your year end videos and tig fingers. I want you to continue making these fantastic videos.
Thanks for the tip about the pedal! I am going to make one for my setup.
All The Best!
Mike
your videos are great dude!!better then a classroom and great content!mig and stick welding for years and going to break into tig.looking at a everlast 211si for the garage after much research😎..
I have the very same Thunderbolt and have a little Tig experience and have always wanted one. Very impressed with the quality of your welds with it. Thinking about giving this a try but or my old boss has a big old Lincoln Tig/Stick that hasn’t been used in about 10 years that he wants to sell me for like 400🤔 Anyway great vid!👍 by the way just to let you know those cuts for round to round are called “saddles” God Bless brother
Can you show how to make a foot paddle? That is a neat trick.
i agree and it gave me a idea how to connect a torch thumb rolling amp switch.
Bloody scratch start the number of times I forgot to start the argon !!! thanks for not editing those bits out honest & open , jody , cheers
I've gotten spoiled by high freq start and a gas solenoid on my everlast welder. Starting and stopping the argon manually is hard to go back to.
Wait until you get a better machine like the invertig 221 the arc is so buttery youll wonder how you went without it.
Great video jody thanks, at work we use our miller 300abp with a scratch start setup. It welds as smooth any new welder on the market
I really like your videos. Im a beginner and am gonna buy the Miller Multimatic because I can mig, tig and stick with it and can't afford to buy separate machines while wanting to weld in all styles. Well thats for now till I make more money and can buy better equipment. Keep these videos coming.
This does work wonders! I have the same thunderbolt - does this task very easily
I learn a lot from you Jody, thank you and GodBlessU always.
Thank god I found this channel. Good, usable information here.
I was hoping to see how to appropriately come out of a puddle with out any form of pedal. This is the last thing that has been defeating me. I work as a TIG hand anywhere that pays and I have yet to see a torch without a valve and the peals just don't exist outside a shop scenario. My little miller diversion 185 babies me and I don't have that problem in the garage scene. The problem being 22 years of age is its hard to look like a pro when I still cant come out of my puddle correctly every time lol being this young generally gets me scrutinized pre-weld-test so I really need to impress. Thanks if you would take that as a suggestion for a video In the future! Always enjoy the videos. Keep it up boss!!
Great video, GREAT footage, thanks for all the details!
My first real stainless TIG project was done on a scratch start Miller Maxstar inverter I borrowed from the local welding store. Never did think of using the rod to start the arc though. Thankfully that machine was modern and automatically started the argon. :-)
This is very interesting. Until recently I didn't know you could TIG with a stick welder. I recently bought a stick welder used (Kemppi 150A DC rectifier from the 80s) to learn with as a stick seemed like the cheapest, most versatile welding you can learn, and now you can TIG with it too? Clearly a stick welder is the best home welding setup it seems!
The pedal is a really nice innovation! Makes me wonder though if they make TIG torches with valves for use with scratch start, why not make a TIG torch with a trigger like a MIG torch? That way you could use your hand to start or stop the welding.
+1873Winchester It would be possible to rig up a micro switch to the torch with tape or zip ties and use that to operate a relay large enough to handle the welding current. You WOULD NOT .... I repeat .... WOULD NOT .... let me repeat that again ... WOULD NOT want to switch the welding current with the micro switch. They aren't made to switch high current loads. You would want a low voltage source .... say 24VAC .... going through the micro switch. You're talking transformers ... relays ... wires .... pretty much a bear skins and stone knives approach but it should work. You could also rig up a foot pedal the same way. Disclaimer .... this was presented for entertainment purposes only. If anybody does this and gets hurt .... it's on you. Electricity can kill you.
going to start welding soon, wish you were my teacher lol. you're very good!
your weldings are so beautifull... thanks !!!
Thanks for the instructive video. Can you put a link to the diy foot conroller please, Richard
Hey Jody, you've helped me out more than you could know, but if you take any requests, I was wondering if you could demonstrate a 7018 hot pass/fill pass on schedule 80 carbon steel. It seems to be my weak point. You did such a great demo of the 6010 root pass, and this would fall under the same pipefitter guidelines
Jody
Reminds me when I played 18 holes of golf with a pro
He played with one club I had a full set and i am not a bad golfer
and still got whacked
so I see what you do and want to be somewhere near there
the tig finger keeps my hands safe
thanks again

since watching your videos, i've tried tig welding with an old miller heliarch, the HF part no longer works so i've been messing steel work. i love it to sat the least, one thing i cannot figure out is when trying to weld square tubing I cant seem to hold a puddle between the rounded side and the square cut. On the butt joints it seems great, barely need filler rod. I'm using a 1/16 tungsten, am i expecting too much heat from too small of electrode or just not good enough yet? Thanks again for your awesome videos
Nice video. Makes me want to set up my Thunderbolt to scratch start TIG.
I am from Algeria and I really like your job
Hi Jody,
This is my favorite channel on welding.
Good quality shots, comments and editing, and, excellent welder too...!
About warping, you were able to make a 90 deg. on the front of the pole (The side where the pipe is welded) But what about the other side? Because, when I tried this, the whole pipe started to bend toward the the welded side ending up with a bowed fixture...
Any suggestions...?
If you get a good deal on a used machine, you use it to learn and, if you have taken good care of it, put it up for sale. Cost of material, near $0.00.
Thanks for the time you spend doing this.
Pierre
one option to limit distortion on a small pipe is to make a strongback. Rigid pipe tools makes something called a pipe welding vise that might give you an idea. It is a casting and uses chains on each end that are snugged with a crank handle.
But you can make something similar...essentially, a piece of channel or wide flange drilled for u bolts on each end and a spacer in the middle. This would be placed on the opposite side of the weld and preloaded by tightening the u bolts.
hard to explain here so I will work on posting something about this
weldingtipsandtricks
Good idea, I get the picture, it's easy to make for cheap with current shop scraps.
I went to see Rigid's site and this what it look's like:

I love learning stuff...!
Thanks,
Pierre
i work for a company that installs a bunch of stuff for food companies like tyson. we install conveyors mostly but we usually do everything they need and this is all we use is scratch start tig and stick for the rails switches and i beams stuff along those lines
That foot pedal is a great idea. Do you have a video on making that?
I'm very interested in this scratch start, got the stuff - just need practice
you have the best video's on welding. I am going to order the video bundle but would like to have the 2014 video's also.
when will you include the 2014 video's in the bundle?
Jody teaches better then the Lincoln' boys. I'd pay to do a in house course with him.
Can you do a build video on the foot petal that’s a awesome idea for scratch start
Hi there. I lock couple of your videos and i must say you do a very nice job. Sometimes your tips realy helps me. But i must do one critic,why you dont use your left hand?
Greatings from Serbia
You have great videos, recently i bought tig tourch and hooked up to my mig, yourch has a button same as mig tourch and i hooked it up so it would power on cable and allso opel electric valve to supplay gas, next thing is to make it pulse a bit, by that i am hoping to limit heat input, because on lowest setting i can melt 2mm plate easly..
if some one wants some more info, send me a message iļl try to explain what i did..
I like it. When I find video like that I wont trying to do it my self, so once I ll do it like my hobby
I have a Thunderbolt and I would love more information on doing tig with it. I also have Argon and a mig welder.
Hey Jody, big fan from New Zealand. Could you possibly do a tutorial on welding pipe on a rolling jig? Mig solid wire with argon. Cheers
what is the argon flow rate? and how do you tell if its right? thanks for the great videos!!!
Wow..I use the hole saw for make a joint angle..good tips..sorry for my english
when ever i have to "scratch start " i dont contact the electrode to the base metal i hold it close and i flick the filler rod contacting the base metal first then across the electrode far less contamination if any. walking the cup is my favorite never gets old.
So do you suggest using a high freq start tig machine for beginners?
merci jody !!
you are one professor
Any chance you can post a video of your homemade foot pedal ?
Jody,fully believe you could produce great welds with a rusty nail and some fence wire!
So I'm totally new to welding and have watch all your videos ( best on UA-cam by far ). I want to buy a Hobart 140 Mig welder. Is there any way you can make a video with one. All I want the welder for is to make a few BBQ pits for friends and family. I'm using 3/8in pipe. Or do you recommend I get the Hobart stick mate for that thick of steel. I just like the mig welder because it runs on 110 house hold current and not 220 like the stick mate.
I'm in need of some of your advice. I'm what you would call a beginner at tig welding I've got roughly 8hrs under my belt. I'm using a tweco 211i, straight argon, 3/32 filler, smaller electrode, and it's scratch start. My troubles are I can't get a good bead going welding a catalytic converter to a down pipe while it's on the vehicle. Are there any tips you can give me?
Hey Jodie (or anybody for that matter), with a foot pedal setup like you have could that be used to initiate the arc too like in lift start? Ya know, for the sake of a clean tungsten? I'm thinking touch the tungsten to work piece, complete the circuit with the pedal, then lift? Or would it just stick? Too much amperage? I want to get into scratch start but I feel like a noob such as myself would just be spending all my time grinding tungstens and I'm trying to think of ways to make things a lil easier/cleaner...thanks!
Another great segment Jody, thanks. Can you talk about welding cast iron with Nichol 99 and a tig set up at some future video? - Fred
het mate I have 2 questions for ya ? number 1. any particular reason you weld your vertical welds in an upwards direction. 2. have you got any hints for single direction tubing welds?
Do you do anything special to electrically protect your knife switch? You mentioned arcing when you close or open the contact with your foot. Does it ball op and make rough spots on the blade that need to be filed off?
I am a down hill pipe welder and run an SA200 on my truck. I picked up a bottle of Argon, a regulator and a W26 heliarc rig. I am having trouble with even making stringer puddles look good on flat plate. walking the cup I can half ass but it is still nothing worth mentioning. I have better looking results up hilling 7018 with a wide puddle. how can I improve? I don't have any one that can work with me locally.
how did you do that foot switch i like it,i don't like the flick away would like to make a foot switch for mine
Ever used a corning machine? It nibbles out notches on tubing like what youre doin.. i used to use it @ a shop that made alot of railings, stuff like that...even great for some chassis building if ya gotcalot of tubing to notch up
i went and checked out the coping calculator it will come in useful is there another one i can use for cutting strait angle's on pipe
Great video as always Jody but would've been better if we got to actually see more "scratch starts" instead of the home made foot pedal. Like the thing you mentioned about striking starting off the filler rod would have been really helpful as we all never stop learning....
Have you had any experience with TIG hard facing? Is it a common practice? You made a video on it? Thanks.
Do you think this same scratch start with knife switch process would work with chrome moly tubing?
that's all they use for all the stainless and mild steel at the Nat Gas power plant we were building in Williston ND. Scratch start hot stick. But if those guys had to weld anything else they don't know how to. They only weld pipe and that is it.
Hello! I'm interested in the DVD and I have been at your store and asked a question at the contact form about shipping costs to Europe... no reply so far...
Tig is cool welding, whats the benefit over using a MIG or stick welder? it reminds me of acetylene welding with a filler rod.
That's a lot to cover in one question lol
Stick welding (im referring to 7018 for the moment) can be run with winds up to 40 mph so its really good for field welds in the elements where its likely to have your gas knocked off your puddle using other welding methods which would really make for a bad day. MIG, in my opinion, is the best of the transfer methods for a shop scenario. Its fast and requires minimum cleaning (before and after.) Because the MIG process has so many adjustments you can make there is a lot of possibility to make welds that would seem difficult in other situations. like a 3/8in gap isn't so scary with a MIG gun in hand. TIG!! There is so much control with tig. It offers the best fusion possibility because your not continually piling on more filler material to sustain the arc there by possibly covering the root, (typically where your would find a slag inclusion for a 7018 root.) you can achieve the resistance you want by adjusting your tungsten to work length, sort of the poor mans pedal, its in my opinion the easiest to get into small areas and make the mirror welds happen. Lastly, the abstract metals are welded with tig much more so for its clarity and quality assurance. Hopefully that answers some questions. There are so many qualities of all 3 methods I have left out that I don't think this little text box could handle. Good luck.
Hey Jody, your foot pedal cutoff is a great idea. Is there any info on how it's made?
+Jeff Lewis I had a duh moment at first. Never saw that before. I would rather make a rheostat pedal control. A blade switch works but wears out fast if you do a lot of switching on/off. In a pinch MacGyver it.
good works
Yeah, would you consider showing a DIY foot switch like the one in the video?
Running purge in a pipe in addition, how well does scratch start do?
Do you have any tips for welding cutting edges on tool steel?
Thank you Jody!
Jody the man thanks Jody 🙏
Is it possible to scratch start on titanium? Doesn't have to be perfect, just want to know if you can get away with it on a bike frame? Thanks, I don't want to waste money ordering the titanium tig wire, I've just got an old welding machine, nothing fancy.
You are the best!!!
What exactly would you recommend for purchase on everything to run rig off of a engine driven welder - looking to get my hand in this have a bunch of carbon coupons pipe -
Can i weld with this setup on AC? Im not sure if my stickwelder is AC or DC but i really want to tig weld for cheap.
Do a similar video using 18 gauge stainless steel tubing instead.Just to show how difficult it is to weld stainless tubing and keep it square👍😃
How did you make the home made foot pedal or did you make a video already?
Great video as always, thank you. A question, if you were to switch welder over to AC could you do aluminum this way? Thanks!
you would need a high frequency unit to maintain the arc . But then you would have to spend as much as it would take to get a newer AC/DC inverter so its not the best way
weldingtipsandtricks
Thanks for the fast come back. On the side, tig fingers I received as a gift work sweet, sweet, sweet! Super product Jody!
Pretty welding I got to learn that.
Can I do a scratch start setup on a Lincoln AC buzz box stick welder to weld some aluminum? Buddy gave me a #17 torch w/ valve, all I see on UA-cam is DC setups like yours but not AC, needing to weld a oil train bung onto a oil pan for my racetruck build, also just wanting to practice tig welding aluminum
AC waveform goes to zero voltage 60 times a second. You need high frequency to keep the arc lit.
If I want to get in cheaply to welding, what is the preferred way?
Thank you dear brother on this video beg you to help me to get an electric arc welding
Would starting arc on carbon rod and moving quick to material work?
can i scratch start tig with 54v stick welding machine ? what is the voltage of tig ,if i weld with 18g stainless steel?
How much output voltage does your machine have?
HAve you covered any videos on welding inconel ?
Every miller I've ever used has had the most unreliable HF start always in for an expensive repair so I don't bother anymore I just use lift or scatch..
You know it is simple to add solenoid to any machine that does not have a solenoid setup.
I also can add Euro connection to any machine that doesn’t have one.
Any tips for welding cutting edges on tool steel
Do you have any lift arc vids?
